LT200 Snapper 18.5 HP won't start (replaced Solenoid and same problem)

Hey everyone,
I figured someone can help before I continue to throw parts at the mower. It would not start. So I tested the solenoid and have power at the yellow wire when I turn the key. I ordered a factory solenoid and replaced it. (Could jump the posts to get it to turn over) However, either I got a bad solenoid out of the bag or another problem. I assume it can be the key tumbler (though I get a test light when I turn the key at the solenoid) The brake switch, seat switch and or PTO switch. Before I start buying part after part was wondering if someone has a way of finding which is the bad component? Any advice in trouble shooting this would be appreciated. Thinking maybe I should bypass the seat and brake switch? Thanks in advance,
Chris

Post year, model & serial numbers as well as all numbers from engine & engine manufacturer. You're absolutely correct, stop changing parts out. If your tractor has B&S engine, you may need to adjust valves per manual specs. If valves are too loose, compression release on camshaft will not work, creating no start problem.
